eAs-sTovE BURNER.

SPECIFICATION forming part of Letters Patent No. 441,537, dated November 25, 1890.

Application filed J'uly 12, 1890.

To aZZ whom, t may concern:

Beit known that I, WARREN L. CORT, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gas-Stove Burners, of which the following is a specification.

The object of my invention is to provide a burner for gas-stoves which shall secure the most complete combustion and the most intense heat without clogging or smoking, and which shall also be of a simple and cheap construction.

It consists in the pecular construction and arrangement of a burner formed of two plates screwed or bolted together and having upwardly extending and inwardly inclined waved edges, whereby a large amount of flame -area is obtained in a given circle.

It also consists in the peculiar construction and arrangement of parts, as hereinafter fully described.

Figure l is a plan view of a port-ion of a gas-stove, showing one of the burners thereof and Fig. 2 is avertic'al section thereof through the line fr fr.

In the drawings, A represents the supportingframe of the gas-stove; B B', the burner; C, the mixing-chamber for air and gas, and I) the inlet-pipe for the gas.

The burner is composed of two annular plates of metal having horizontal flanges b b at their lower edges, which have tongue=and groove connections and bolts or screws b2 for clamping them together. This tongueandgroove connection, with a suitable packing of asbestus and a luting or cement at the joint of. the two plates, forms a perfectly-tight joint all around the burner that prevents the escape of the gas. The burnerplates B B eX- tend upwardly and inwardly toward the center, and their upper edges are waved and form a continuous waved escape-Orifice of general circular form, through which the air and gas issue and burn. At one side the two annular sections B 'B' are formed with halves b3 b4 of a pipesection, which arebolted together similar to plates B B and terminate in iianges b5 h6, which fitagainst a perforated lip or skirt e of the main frame and are bolted through to a flange c of the mixing-chamber C on the outside of the main frame, the joints being ground and made tight by a packing seria No. 358,586. (No model.)

of asbestus and cement. This mixing-chamber is formed with a swelled portion c', formed in one and the same piece with the plug-cas` ing c2 of the stop-cock E. The mixing=cham ber has holes formed on one side of its swelled portion c to admit air, which becomes mingled with the gas issuing from a central nozzle c3, the flow of which gas is regulated by the stop-cock.

The operation of my burner is as follows: The air and gas commingled in proper proportions for complete combustion pass to the space between the two plates B B of the burner, and, iilling this annular space, the mixture rises and issues in a waved sheet at the top of the burner, which burns with a waved Iiame in which a large zone of green exists, and no unconsumed carbon is formed, thus indicating perfect combustion, intense heat, and a very great area of flame-surface within a given compass.

The advantages of this form of burner are that the conimingled air and gas ascend toward the point of escape with arapid motion unretarded by overhanging obstruction, and at the same time the waved slit or annular orifice gives increased clearance for the'issuing gas and anlincreased area of flame, which tends to greatly stimulate the activity of combustion and the generation of heat without deposition of carbon.

lVith reference to the inward inclination of the waved walls of the burnerI would state that while it admits of a large burnercham ber and a large clearance foi` the escape of gas this inward inclination brings a large amount of iiame within a comparatively small circle, concentrating and intensifying the heat beneath the comparatively small bottom of a pot or kettle. Furthermore, this inward TOO against the inner face of said lip, a mixing-chamber having a anged abutting face fitting against the outer face of the said lip, and bolts and nuts for clamping the two iianges tightly together upon the lip or skirt of the main frame, substantially as shown and described.

The above specification of my invention signed by 111e in the presence of two subscribing witnesses.
